Allow peek content to scroll about bottomsheet HOT 4 CLOSED

Can you give some use cases for either of these?

from bottomsheet.

Sure. In my case I'm extending bottom sheet to make a shopping cart.

When an item is added, the cart slides up into "peek". This basically is a list view. I've extended the peek size to either be the height of this product list or the maximum size that would be found if the view was expanded. Conversely, the product scrollview also sizes itself to the maximum size of the parent view too.

The end result is a a scroll list of products. When drag the view into an "expanded" state the payment methods from your account are revealed below and you've moved into checkout mode. If you drag back down you move back into cart mode. If you dismiss the view you're back into buy mode.

So in my case, I need to have a similar action to expanded. Where while in peeked if you drag up or down, it passes that event to the sheet unless the sheet isn't scrollable, upon which it then drags the bottomSheetView into expanded or hidden states.

This is a very cool library and I think it would also be very handy to further add a dynamic element to attach it to any side. I could see uses with top-down peeks as well as left or right peeks.

Again, thanks for the open source.

This wouldn't really work with how the library works. When the bottom sheet is created, its height is actually the same as the parent. This creates an issue where if you wanted to scroll the list in its peeked state, the bottom n items of the list would conceivably never be visible in the peeked portion, since they're considered visible in the context of the whole sheet itself. The sheet isn't really expanding when you pull it up, rather you're just translating it up from off-screen.

A potential work around for this would maybe be to allow for scrolling until it hits the bottom, and then continuing the scroll by translating the sheet up. I think this behavior would be weird and not exactly obvious, so I don't think it's something we want to figure out just for a niche use case. You'd probably be better off extending BottomSheetLayout and implementing this behavior yourself.

There's something for that in the material spec and support library already. It's called the Navigation Drawer ;)

Going to close this for now, we can revisit if more people express an interest.
